Abstract: PURPOSE:To prevent disconnection of lead wires and coaxial lines by detaining a sound transmission tube as an antenna on a printed circuit board in a main housing and bringing this tube into contact with a conductive flat spring connected to the circuit of the board slidably. CONSTITUTION:A microphone 10 for transmission is provided in a main housing 1, and a transmitter 21 is provided in an open/close arm 6 freely openably and closable coupled to the main housing 1, and a metallic sound transmission tube 22 is provided which has one end fixed to the transmitter 21 and has the other freely turnably fitted to the microphone 10 for transmission. This sound transmission tube 22 is detained on a printed board 13 in the main housing 1 as the antenna and is brought into contact with a conductive flat spring 23 connected to the circuit of this board slidably. Consequently, a torsional force does not act upon the sound transmission tube because of slidable contact between the sound transmission tube 22 and the microphone 10 for transmission and between the sound transmission tube 22 and the conductive flat spring 23 through the open/close arm 6 is turned. Thus, the disconnection due to torsion accompanied with opening and closing of the open/close arm is prevented.

Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve durability of a power transmission device and reliability of interruption of power transmission without adopting an overload rupture possible material. SOLUTION: In steady operation, when a pulley 7 is rightward rotated, a groove 8A of a fixed pawl 8 of the pulley 7 presses in a right direction a tip end part 9A of a turn pawl 9 supported turnably by a support pin 10 to a boss 4. The turn pawl 9 tends to turn to the right with the support pin 10 serving as the center, but a first plate spring 11 impedes a right turn of the turn pawl 9. Accordingly, with a condition shown by the drawing (a) left as maintained, a total unit is right rotated. At abnormality time, even when the pulley 7 is right rotated, the boss 4 can not be rotated. Thus by strong pressing the tip end part 9A of the turn pawl 9 to the groove 8A of the fixed pawl 8, the turn pawl 9, with the support pin 10 serving as the center, while resisting pressing force of the first plate spring 11, is right turned.  When the turn pawl 9 is turned by a prescribed angle, the tip end part 9A of the turn pawl 9 is detached from the groove 8A of the fixed pawl 8, simultaneously with a second plate spring 13 locking a lock shoulder 9C of the turn pawl 9.
